SCI to USB Board

Host interfaces with Windows, Mac, and Linux computers is supported by FTDI's virtual com port or HID driver set. When used with common PC terminal programs, communications with the host computer appears as a virtual serial port. CTS and RTS flow control are implemented along with RX / TX status indicators.

The device is compatible with both 3.3V and 5V processors. With no host device connected, the FTDI chip is held in reset. Upon connection to a host device, the reset is released and the USB chip automatically enumerates the USB communications link with the host computer. From the embedded programmer's perspective, communications entails normal SCI communications protocol (i.e. drivers written for RS232 interface work equally well with the USB peripheral). USB programming is achieved with FTDI's programming utility, run via a host computer. For additional information, refer to the FTDI 232RL data sheet.
